Mindful Parenting And Toddlers' Food Responsiveness: The Role Of Controlling Feeding Practices, Qingyu Jiang, Holly Wilhite, Natalie A. Williams, Dipti A. Dev, Caron A. C. Clark, Pearl Avari, Sarah B. Ladd Aug 2026

Mindful Parenting And Toddlers' Food Responsiveness: The Role Of Controlling Feeding Practices, Qingyu Jiang, Holly Wilhite, Natalie A. Williams, Dipti A. Dev, Caron A. C. Clark, Pearl Avari, Sarah B. Ladd

Journal of Extension

Controlling feeding practices may negatively impact children's eating behaviors. Mindful parenting may offer a promising way to reduce the use of these practices. This study examined the mediating role of pressuring children to eat and using food as a reward in the association between mindful parenting and toddlers' food responsiveness. Results indicated that higher levels of mindful parenting were associated with lower pressuring to eat, which was related to lower food responsiveness in toddlers. The results may inform Extension professionals providing mindfulness strategies for mothers of young children to improve feeding practices, ultimately reducing children's unhealthful eating behaviors.

Department of Neurology Faculty Papers

OBJECTIVES: Multiple sclerosis (MS) is a complex, progressive neurodegenerative autoimmune disease and a major cause of neurological disability worldwide. MS affects approximately 2.8-3 million people, predominantly presenting as relapsing-remitting MS (RRMS) that frequently converts to secondary progressive disease, while effective options for progressive phenotypes remain limited.

METHODS: This review reframes MS immunotherapy through a tolerance-centric paradigm, distinguishing continuous maintenance disease-modifying therapies (DMTs) from immune reconstitution therapies (IRTs) and emerging antigen-specific tolerance strategies.

RESULTS: Classical immune reconstitution therapies, including alemtuzumab, cladribine, and autologous hematopoietic stem cell transplantation (aHSCT), have demonstrated durable disease control and prolonged periods of no evidence of disease …


Acemannan/Alginate Composite Hydrogels Promote Sto Cell Spreading And Metabolic Activity, Hong Yongxing, Tharasanit Theerawat Aug 2026

Acemannan/Alginate Composite Hydrogels Promote Sto Cell Spreading And Metabolic Activity, Hong Yongxing, Tharasanit Theerawat

The Thai Journal of Veterinary Medicine

Alginate-based hydrogels are widely used as biocompatible scaffolds. However, their limited cell-adhesive properties restrict their application in tissue engineering. This study aimed to fabricate acemannan/alginate (ACE/ALG) composite hydrogels and evaluate their cytocompatibility and ability to support STO cell spreading and metabolic activity. Composite hydrogels were prepared by blending different concentrations of ACE with alginate, followed by Ca²⁺-mediated ionic crosslinking. Rheological analysis showed that ACE incorporation increased both the storage modulus (G′) and loss modulus (G″) of the hydrogels. Cell viability and morphology were evaluated using Live/Dead staining on day 7, and cellular growth was assessed using an MTT assay on …

The Thai Journal of Veterinary Medicine

Contamination of chicken meat with antimicrobial-resistant bacteria, particularly multidrug-resistant (MDR), colistin-resistant, and extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli), threatens its safety for human consumption. This study was conducted to determine the prevalence and antimicrobial resistance (AMR) profiles, particularly ESBL production and colistin resistance in E. coli isolated from retail chicken meat in fresh markets in Bangkok, Thailand. A total of 200 (81.6%) E. coli isolates were recovered from 245 chicken meat samples collected from fresh markets across six regions of Bangkok. Among the isolates, 189 (94.5%) exhibited resistance to at least one antimicrobial agent tested, with the …


The Lottery You Do Not Want To Win: The Role Of Local Institutional Quality In Brazil's Fight Against The Persistent Transmission Of Poverty, Adaye Sosthene Yvan N'Guettia Aug 2026

The Lottery You Do Not Want To Win: The Role Of Local Institutional Quality In Brazil's Fight Against The Persistent Transmission Of Poverty, Adaye Sosthene Yvan N'Guettia

Economics Honors Projects

When does improving local institutions increase the poverty-reducing effectiveness of transfers? This paper examines whether federal oversight strengthens municipal administration of anti-poverty programs in Brazil. I develop a governance model in which incumbents allocate resources across diversion, effort, and institutional investment under audits and incentives. Using exogenous variation from Brazil's random CGU audit lottery across 5,500 municipalities, I find audits reduce irregularities, strengthen capacity, improve nutritional monitoring and school infrastructure, and reduce extreme poverty — with effects largest in municipalities with weakest institutions. A marginal-value-of-public-funds analysis confirms the program is self-financing. Results show the poverty-reducing power of transfers depends critically …


Symbol Of Defiance: Cultural Reclamation And Resilience In The Symbolism Of The Watermelon, Shukri Mohamed Aug 2026

Symbol Of Defiance: Cultural Reclamation And Resilience In The Symbolism Of The Watermelon, Shukri Mohamed

Gatherings

This paper examines the watermelon as a cross-cultural symbol of nonviolent resistance and identity reclamation in both Palestinian and African American contexts. In Palestine, the watermelon embodies defiant cultural identity amidst occupation, symbolizing resistance against erasure. Within African American communities, it has evolved from a racially charged stereotype to a reclaimed symbol of pride and agency. Through postcolonial theory, intersectionality, transnational feminism, and visual cultural critique, this article examines how marginalized groups repurpose familiar objects to assert identity and reclaim autonomy under oppressive conditions. Drawing on Lila Abu-Lughod's work on media and everyday resistance, Ania Loomba's postcolonial perspectives, Patricia Hill …


Embodying Palestinian Freedom: Yogis For Palestine As A Site Of Transnational And Anti-Imperial Feminist Solidarity, Sheena Sood Aug 2026

Embodying Palestinian Freedom: Yogis For Palestine As A Site Of Transnational And Anti-Imperial Feminist Solidarity, Sheena Sood

Gatherings

In a climate marked by the rise of global fascism, yoga is often appropriated toward the reproduction of caste supremacist and ethnonational agendas, colonial and racial capitalist relations, and neoliberal spirituality. Still, it has also been harnessed for collective liberation. We see this through the effort of Gaza-based yoga teacher, Hadeel Al-Gharbawi, using trauma-informed yoga to help the children of Al-Jawad Camp cultivate endurance during a genocide, and the solidarity of practitioners activating yoga toward Palestinian self-determination. This article examines the social and political activities of Yogis for Palestine (YFP), a Philadelphia-based collective whose vision for collective liberation includes unwavering …

Equity In Evaluation: Examining Grading Practices And Student Experiences In Speech-Language Pathology Education, Jennifer Essig

Teaching and Learning in Communication Sciences & Disorders

Traditional grading practices remain the norm in communication sciences and disorders (CSD) education, despite evidence these systems may exacerbate inequities and affect motivation and perceptions of learning. This study examined how traditional and alternative grading practices are experienced by undergraduate and graduate students enrolled in CSD programs. Using a convergent mixed-methods design, survey data were collected from 73 students regarding perceptions of grading, motivation to learn, and emotional responses to assessment. Quantitative analyses indicated that students in alternatively graded classrooms reported significantly higher perceptions of fairness, clarity, and learning than those in traditionally graded settings. Qualitative analysis revealed contrasting emotional …


Targeted Interprofessional Education (Ipe) Curriculum For First-Year Speech-Language Pathology (Slp) Graduate Students, Cody Marie Busch Aug 2026

Targeted Interprofessional Education (Ipe) Curriculum For First-Year Speech-Language Pathology (Slp) Graduate Students, Cody Marie Busch

Teaching and Learning in Communication Sciences & Disorders

ASHA requires that SLP graduate programs facilitate opportunities for interprofessional collaborative practice (IPCP). Research suggests that IPCP initiatives should be integrated throughout the curriculum, rather than isolated interprofessional education (IPE) experiences. 15 first-year SLP graduate students participated in a year-long IPE curriculum focused on the IPEC Core Competencies. Quantitative and qualitative data revealed improved perception of IPCP and appreciation of opportunities to interact with other disciplines. Students noted that SLP graduate programs should integrate IPCP opportunities because they set them up for success with collaboration and help remove the SLP “silo.” Finally, students reported that they plan to use the …

An Exploration Of Case-Based Teaching And Learning In Aac Courses: Student Data Analysis And Reflections On Engaging In Academic Research, Kayla Lorance, Claire Almos, Abigail Spudich, Alli Sauerwein, Kristen Muller

Teaching and Learning in Communication Sciences & Disorders

Case-based learning is a beneficial pedagogical approach because it offers opportunities for students to apply constructs and frameworks and to develop clinical reasoning and decision-making skills. Clinical cases have been used to explore students' clinical reasoning skills in AAC research studies; however, few instructors have published about the use of case-based learning in their AAC courses. Thus, this study aimed to understand how and why faculty and instructors use case-based learning in graduate-level AAC courses as well as their recommendations for colleagues.

A total of twelve faculty participated in the study by completing an interview. Qualitative data analysis was completed. …

Simulated Participant Engagement In Communication Sciences & Disorders Programs: A Scoping Review, Jason Konzelmann, Richard I. Zraick

Teaching and Learning in Communication Sciences & Disorders

Introduction. Simulated participants (SPs) are widely used in medical and nursing education, but their application in allied health, including Communication Sciences and Disorders (CSD), remains limited. Despite accreditation standards supporting simulation in CSD training, student engagement with SPs is still uncommon.

Objectives. This scoping review examined recent literature on SP use in CSD programs involving speech-language pathology or audiology students or providers. We explored how SPs were integrated and identified gaps for future research.

Methods. Guided by PRISMA-ScR, we searched six databases and an internet search yielded one additional article. Studies published between 2019 and 2025 were included if they …


Conserving Seabirds: Actions Of The Pacific Seabird Group During Its First 40 Years., Craig S. Harrison Aug 2026

Conserving Seabirds: Actions Of The Pacific Seabird Group During Its First 40 Years., Craig S. Harrison

Marine Ornithology

The Pacific Seabird Group (PSG), founded in 1972, is “dedicated to the study and conservation of Pacific seabirds and their environment.” During its first 40 years, PSG undertook scores of conservation actions, although as an all-volunteer organization, PSG lacked the capacity to implement many programs or projects. It achieved its conservation goals through leadership, raising issues, bringing the best science to decision makers, and serving as a catalyst for others to act. PSG has been especially influential in six areas: (1) eradicating invasive alien animals from seabird colonies; (2) conserving Marbled Murrelets Brachyramphus marmoratus; (3) protecting seabird colonies in …

Marine Ornithology

The Galapagos Penguin Spheniscus mendiculus, endemic to the Galápagos Archipelago, faces increasing ecological pressures threatening its population. This study aimed to characterize its daily behavioral patterns to better understand its adaptations and vulnerability to ecosystem changes. In one breeding locality, the Marielas Islets, we mounted a Crittercam on a male penguin to assess interactions with its mate and its behavior over a 24-hr period. Behaviors were classified as Diving, Foraging, Grooming, Intraspecific Interaction, Interspecific Interaction, Loafing, Prospecting, Resting, Surface Dipping, and Swimming. We analyzed behavioral data using chi-square tests and transition heat-maps. Results revealed predominantly surface behaviors—Prospecting (41.2% of …


Comparing Counts Made From Drone-Based And Boat-Based Photography For Surveying Thick-Billed Murre Uria Lomvia Cliff Colonies., Ewan Macdonnell, Sarah E. Gutowsky, Kyle H. Elliott Aug 2026

Comparing Counts Made From Drone-Based And Boat-Based Photography For Surveying Thick-Billed Murre Uria Lomvia Cliff Colonies., Ewan Macdonnell, Sarah E. Gutowsky, Kyle H. Elliott

Marine Ornithology

Surveys of cliff-nesting seabirds from sea level or ground level often miss individuals hidden by topography, leading to underestimates of abundance. Thick-billed Murres Uria lomvia are especially challenging to survey accurately due to their dense nesting on vertical cliff ledges in remote northern regions. In Canada, updated colony surveys are needed, as currently used population estimates, done from boats, are outdated. Drones offer better vantage points and may reduce availability bias (i.e., the proportion of birds present but not visible), but direct comparisons with boat-based counts are essential. We compared murre counts from drone- and boat-based photographs of six vertical …

Marine Ornithology

The foraging areas used by adult Sooty Terns Onychoprion fuscatus during incubation and early chick-rearing on Bird Island, Seychelles, were investigated using small GPS loggers. Birds departed the colony mainly during the night and foraged by day. Most foraging trips were completed within 24 hr, but during incubation the longest duration recorded was seven days and 14 hr (during which the bird travelled 2,783 km and reached a maximum of 692 km from the colony). Departures were generally in an arc from south (180°) through westerly to 40°. Sooty Terns foraged frequently in waters over the Seychelles Bank shelf break, …


First Record Of Leucism In Kerguelen Shag Leucocarbo Verrucosus, Kevin Guille Aug 2026

First Record Of Leucism In Kerguelen Shag Leucocarbo Verrucosus, Kevin Guille

Marine Ornithology

The first case of leucism in the Kerguelen Shag Leucocarbo verrucosus was observed on Mayes Island, Kerguelen Archipelago, in the southern Indian Ocean between October 2021 and November 2022. The individual exhibited extensive white plumage with scattered black feathers while maintaining normal eye pigmentation, consistent with leucism rather than albinism. Despite exhibiting typical behavior and social interactions, no breeding activity was recorded. This observation highlights the occurrence of pigment abnormalities in sub-Antarctic seabirds and underscores the importance of continued monitoring to better understand their ecological or genetic implications.
